COMBINED FRlTlCN AND DIRECT-ACTING DR/-lFT-RKEGIING.

SPECIFICATION forming part of Letters Patent No.71 7,679, dated January 6, 1903. Application filed November 16, 1902;. Serial No. 131,460. (No model.)

Beit knownithat I, JOHN J HENNEssEY, a citizen of the United States, residing in Milwaukee,in the county of Milwaukee and State of Wisconsin, have invented a new and use-Vv ful Improvement in a Combined Friction and Direct-ActingDraftRigging,of which the following is a specification.

Myinventionrelates to friction spring draftrigging for railway-cars. The object of my invention is to provide a combined friction and direct-acting spring draft-rigging of a simple, compact, strong, efiicient, and durable construction capable of being cheaply manufactured and quickly and conveniently applied to the car.

My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with the draw-bar anddraft-iron in lineV therewith having a straight friction-face on one side and double-incline friction-faces on its opposite side, a stationary friction plate or face engaging the straight friction-face of the draft-iron, a transversely-movable friction-block having double-incline frictionfaces engaging the double-incline frictionfaces on the draft-iron, a transversely-arranged spring acting against said frictionblock, a longitudinally-arranged direct-acting spring and followers therefor on the opposite side of the draft-iron from said transversely-movable friction-block, of side plates or stop castings provided with transverse guides for the transversely-movable frictionblock and with longitudinal guides and stops for the followers of the longitudinal or directacting spring, the longitudinal guide for said direct-acting spring and followers having an opening closed bysaid stationary frictionplate for the admission and removal of the direct-acting spring and its followers.

My invention also consist-s in the novel construction of parts and devices and in the novel combinationsof parts and devices herein shown or described.

In the accompanying drawings, forming a part of this specification, Figure l is a vertical longitudinal section of a combined friction and direct-acting spring draft-rigging embodying my invention, the section-line being indicated by the line l 1 on Fig. 2. Fig. 2

isa plan View, partly in horizontal section, on line 2 2 of Fig. l. Fig. V3 is across-section on line 3 3 of Fig. l. Fig. et is a detail perspective view of the side plates or stop-castings.

.y Fig. 5 is a detail perspective view of the stationary friction-plate. Fig. 6 is a detail perspective view ofl the thiinble. Fig. 7 is a detailperspective of the stem or rod which extends through the direct acting spring.

Fig. 8 is a detail view of one of the followers.

In said drawings, A represents the drafttimbers; A', the center sills; A2, the crosssills; A3, the buffer-block, and A5 the carryiron.

B is the draw-bar of the coupler B D is the sliding friction draw-bar extension or draft-iron, the same being directly in line with the draw-bar and connected thereto by the clip or yoke b passing through an eye d in the draft-iron, the cross-pivot d of which eye is slightly rounded or beveled, so that the draw-bar and coupler may have the necessary slight lateral vibratory movement as well as a slight vibratory movement up and down.

F F are the side plates or stop-castings litting between the draft-timbers and Asecurely attached thereto by bolts f. The draft-iron D has a straight .friction-face d2 on one side, preferably its upper side, which is in sliding frictional engagement with the stationary but removable friction-plate G, which is securely fixed or anchored on the side plates or stop-castings F F. The draft-iron D has on itsopposite side from the said friction-face d2, and preferably on its lower side, double-ineline friction-faces o? di, which'coperate with the double-incline friction-facesh h on the transversely-movable friction-block H, which is acted upon by the transversely-arranged spring K. The friction-block H has a barrel or liange h2 to receive the spring K, which is supported at its lower end by a spring-seat or cup K', which is removably secured to the side plates or stop-castings F by cctter bolts or pins K2, extending through suitable lugs f3 on the side platesor stop-castings and provided with keys K3. The side plates or stopcastings have transversely-extending guides f4 for the friction-block to reciprocate in or on transversely while holding the same in position longitudinally in respect to the drawbar or draft-iron.

IOL]

The side plates or stopcastings F F are provided directly above or opposite the friction-block and its transverse guides f4 with an integral longitudinal guide f5 to receive the longitudinally-arranged Cli- :rect-acting spring N and its followers P P. The longitudinal guide f5 is preferably in the form of a case or housing to cover and inclose the spring N and followers P P, and it has an opening]C6 at its bottom for the admission and removal of the spring N and followers P P, which is closed by the removable stationary friction-plate G, said plate G having a shouldered or raised portion g fitting within said opening f and serving to anchor said friction-plate in place. The stationary friction-plate G thus serves to support and guide the followers P P, as well as to afford a friction-surface for engagement with the straight friction-face d2 of thedraft-iron. The closed ends or headsff7 of the longitudinal guide f5 act as stops for the followers P P. A smaller spring N may be inclosed within the spring N, if desired. The followers P P are operated by central upright wings d5 on the draft-iron acting against the removable thimbles P', which are interposed between the followers P and said central upright wings on the draft-iron. The thinibles P' have sockets p to receive the stem or rod p2, which extends through the springs N N. These thimbles are also preferably provided with flanges p3 to give a larger bearing against the followers. The thimbles may be made in a separate piece from the followers, as this facilitates the removal and insertion of the followers in the closed guide]p5 The two side plates or stop-castings F F are securely bolted together at their meeting faces by bolts f8, thus adding strength and rigidity to the draft-rigging as a whole.

The draft-iron D is provided with a central web Z2-bridging the incline friction-faces d3 d4, to strengthen the draft-iron, said web fitting in a corresponding slot formed in the friction-block H.

To cause the direct-acting spring N to come first into action under either pulling or buffing strains and the transversely-acting spring and friction-block to come subsequently into action, the incline friction-faces d3 dl on the draft-iron are more widely separated than the cooperating friction-faces h 72, on the frictionblock, thus leaving some play for partial compression of the longitudinal directacting spring before the friction-block begins to compress the transverse spring K, and as the downward or transverse movement of the friction-block H is somewhat less than that of the followers P, I prefer to so arrange the parts that the direct-actingspringNis slightly or partially compressed when applied or assembled, as this enables me to use springs of the same size and length and still have both fully compressed by the full movement of the draft-iron, thus utilizing the entire strength of both springs.
